--- Comment #4 from Patrick McFarland diablod3@gmail.com 2010-12-01 16:01:36 CST --- There are no ATI bugs currently in SupCom2. I just played through the entire single player campaign, and there were no rendering bugs that I noticed.
Unless the submitter can confirm he still has this bug on nvidia hardware, I suspect it can be closed as fixed.
